Question 341863: A car is traveling on a road that is perpendicular to a railroad track. When the car is 30 meters from the crossing, the car's new collison dector warns the driver that there is a train 50 meters from teh car and heading toward the same crossing.

You can put this solution on YOUR website! The car , the crossing & the train are at right angles to each other.
the hypotenuse = 50 m
the leg =30 m
other leg = (sqrt(50^2-30^2)
sqrt(2500-900)
=sqrt 1600
=40 m.
Train is 40 m from the crossing
